I'm going to college very soon and I would like to spend my free time learning useful skills that could benefit me when I operate during the night.
Skills, unlike possessions don't take space and always travel with you, that's why I value them more tan things (I'm a bit of a minimalist).
Sure, I could play football like everybody else, but it would be absolutely useless for SHTF situations, survival or night opping.

I've made a little list of useful things that I will try to learn (bear in mind that I live in Europe where such things as firearms are heavily controlled):

First, let’s talk about fighting, I’ve done some research based on which martial arts were the most useful (see the links below) and on which ones the gyms in my city offered. I’ve narrowed it down to 3 martial arts/combat systems :

- Krav-Maga to learn to quickly defend myself against weapons, multiple opponents.
- Boxing (French or English) to learn how to throw proper punches (and kicks).
- Wrestling because in case I fall, I can still fight effectively.

In the last vid, you can clearly see that the tall guy (a wrestler) is having a massive advantage over the short one (Muay Thai world champion) when they both go on the ground.
Being able to defend yourself is paramount, especially with the now massive amount of fucking refugees/rapists/murderers who come to Europe (thanks liberals...), when you’re skinny like me, you should go to the gym to get bigger and learn to fight bigger/stronger opponents.

On that note, I will, of course, go to the gym a few times per week and go for a run once a week to build up stamina.

I will learn to shoot and disassemble all gun types (pistol, revolver, shotgun, sniper rifle,...) and get my certificate in order to posses one (thanks stupid EU gun laws).

I will take scuba diving lessons to get my PADI diver certification.

I will learn to fly a small plane (think Cessna 150 or alike), I will only learn to do it, and I will not be getting a flying permit since it’s very expensive.

I’m learning to pick up girls, which could seem stupid, but you would be surprised if I told you that knowing how to pick up chicks had a lot of other uses (business, social engineering, intel gathering). Those channels can be useful to learn it, but nothing beats real life
experience :

I’m trying to find ways to earn money while travelling (night opping being one of them), I could also use night opping skills to be some sort of private investigator who could break the rules and bring better results than the “legal ones”.

I would like to be, by the time I’m 25, some sort of a nomad, who does what he wants, when he wants, with who he wants, a free happy man basically. All the skills listed above would be part of me and I could use them when I want to. No money? No problem, let’s do some night opping to earn some. See a girl that you like? Pick her up. Somebody puts a gun to your head? Beat the shit out of him. Combining all those skills with travel would be an ultimate life goal (think James Bond, but with a leather jacket instead of the suit in order to blend in when I need to). A good player hides his hand...

I listed the skills that I think would be useful, feel free to post your suggestions/critics in the comments and thank you.

Well, the time frame would be something like 2 to 3 years (for the martial arts at least) and a shorter amount for diving/shooting.
I go to the gym already, and I do Krav Maga, so, first, I will take boxing lessons, learn to shoot and do night opping.
Because I have a lot of free time after my college classes and since the school year is only starting in 2 months, I have a lot of time.
